boost::urls::params_base::find

Find a matching key

Synopsis

Declared in <include/boost/url/params_base.hpp>

iterator
find(
    core::string_view key,
    ignore_case_param ic = = {}) const noexcept;

Description

This function examines the parameters in the container to find a match for the specified key. The comparison is performed as if all escaped characters were decoded first.

The search starts from the first param and proceeds forward until either the key is found or the end of the range is reached, in which case `end()` is returned.

assert( (*url_view( "?first=John&last=Doe" ).params().find( "First", ignore_case )).value == "John" );
return this->find( this->begin(), key, ic );

Linear in `this‐>buffer().size()`.

Return Value

an iterator to the param

Parameters
